Selected AbstractsPure Contagion and Investors' Shifting Risk Appetite: Analytical Issues and Empirical EvidenceINTERNATIONAL FINANCE, Issue 3 2002Manmohan S. Kumar This paper discusses a ,pure' form of financial contagion, unrelated to economic fundamentals , investors' shifting appetite for risk. It provides an analytical framework for identifying changes in investors' risk appetite and discusses whether it is possible to directly measure them in a way that can enable policy makers to differentiate between financial contagion and domestic fundamentals as the immediate source of a crisis. Daily measures of risk appetite are computed and their usefulness in predicting financial crises is assessed. [source] Alcohol and mortality: methodological and analytical issues in aggregate analysesADDICTION, Issue 1s1 2001Thor Norström This supplement includes a collection of papers that aim at estimating the relationship between per capita alcohol consumption and various forms of mortality, including mortality from liver cirrhosis, accidents, suicide, homicide, ischaemic heart disease, and total mortality. The papers apply a uniform methodological protocol, and they are all based on time series data covering the post-war period in the present EU countries and Norway. In this paper we discuss various methodological and analytical issues that are common to these papers. We argue that analysis of time series data is the most feasible approach for assessing the aggregate health consequences of changes in population drinking. We further discuss how aggregate data may also be useful for judging the plausibility of individual-level relationships, particularly those prone to be confounded by selection effects. The aggregation of linear and curvilinear risk curves is treated as well as various methods for dealing with the time-lag problem. With regard to estimation techniques we find country specific analyses preferable to pooled cross-sectional/time series models since the latter incorporate the dubious element of geographical co-variation, and conceal potentially interesting variations in alcohol effects. The approach taken in the papers at hand is instead to pool the country specific results into three groups of countries that represent different drinking cultures; traditional wine countries of southern Europe, beer countries of central Europe and the British Isles and spirits countries of northern Europe. The findings of the papers reinforce the central tenet of the public health perspective that overall consumption is an important determinant of alcohol-related harm rates. However, there is a variation across country groups in alcohol effects, particularly those on violent deaths, that indicates the potential importance of drinking patterns. There is no support for the notion that increases in per capita consumption have any cardioprotective effects at the population level. [source] From "New Institutionalism" to "Institutional Processualism": Advancing Knowledge about Public Management Policy ChangeGOVERNANCE, Issue 4 2006MICHAEL BARZELAY Research on public management reform has taken a decidedly disciplinary turn. Since the late 1990s, analytical issues are less often framed in terms of the New Public Management. As part of the disciplinary turn, much recent research on public management reform is highly influenced by the three new institutionalisms. However, these studies have implicitly been challenged by a competing research program on public management reform that is emphatically processual in its theoretical foundations. This article develops the challenge in a more explicit fashion. It provides a theoretical restatement of the competing "institutional processualist" research program and compares its substantive findings with those drawn from the neoinstitutionalisms. The implications of this debate about public management reform for comparative historical analysis and neoinstitutional theories are discussed. [source] The Metamorphoses of Agrarian CapitalismJOURNAL OF AGRARIAN CHANGE, Issue 1 2002Jairus Banaji Book reviewed in this article: Daniel Thorner (ed.), Ecological and Agrarian Regions of South Asia circa 1930 Daniel Thorner's agrarian atlas of India, fully prepared for the press by 1965, was belatedly published two decades later thanks to the untiring efforts of Alice Thorner. The heart of the atlas consists of a series of descriptions written by the historian Chen Han-seng to illustrate his division of the subcontinent into 21 agrarian regions. The review begins by describing Chen's regionalization and conveying some sense of the quality of his descriptions of individual regions. It then raises analytical issues related to Chen's understanding of agrarian capitalism and his reluctance to characterize developments in the late colonial countryside in terms of the growth of capitalism. The conclusion contrasts two conceptions of agrarian capitalism, rejecting the idea of a historical prototype. [source] Outcomes of the International Union of Crystallography Commission on Powder Diffraction Round Robin on Quantitative Phase Analysis: samples 1a to 1hJOURNAL OF APPLIED CRYSTALLOGRAPHY, Issue 4 2001Ian C. Madsen The International Union of Crystallography (IUCr) Commission on Powder Diffraction (CPD) has sponsored a round robin on the determination of quantitative phase abundance from diffraction data. Specifically, the aims of the round robin were (i) to document the methods and strategies commonly employed in quantitative phase analysis (QPA), especially those involving powder diffraction, (ii) to assess levels of accuracy, precision and lower limits of detection, (iii) to identify specific problem areas and develop practical solutions, (iv) to formulate recommended procedures for QPA using diffraction data, and (v) to create a standard set of samples for future reference. Some of the analytical issues which have been addressed include (a) the type of analysis (integrated intensities or full-profile, Rietveld or full-profile, database of observed patterns) and (b) the type of instrument used, including geometry and radiation (X-ray, neutron or synchrotron). While the samples used in the round robin covered a wide range of analytical complexity, this paper reports the results for only the sample 1 mixtures. Sample 1 is a simple three-phase system prepared with eight different compositions covering a wide range of abundance for each phase. The component phases were chosen to minimize sample-related problems, such as the degree of crystallinity, preferred orientation and microabsorption. However, these were still issues that needed to be addressed by the analysts. The results returned indicate a great deal of variation in the ability of the participating laboratories to perform QPA of this simple three-component system. These differences result from such problems as (i) use of unsuitable reference intensity ratios, (ii) errors in whole-pattern refinement software operation and in interpretation of results, (iii) operator errors in the use of the Rietveld method, often arising from a lack of crystallographic understanding, and (iv) application of excessive microabsorption correction. Another major area for concern is the calculation of errors in phase abundance determination, with wide variations in reported values between participants. Few details of methodology used to derive these errors were supplied and many participants provided no measure of error at all. [source] Intergenerational class mobility in contemporary Britain: political concerns and empirical findings1THE BRITISH JOURNAL OF SOCIOLOGY, Issue 4 2007John H. Goldthorpe Abstract In Britain in recent years social mobility has become a topic of central political concern, primarily as a result of the effort made by New Labour to make equality of opportunity rather than equality of condition a focus of policy. Questions of the level, pattern and trend of mobility thus bear directly on the relevance of New Labour's policy analysis, and in turn are likely be crucial to the evaluation of its performance in government. However, politically motivated discussion of social mobility often reveals an inadequate grasp of both empirical and analytical issues. We provide new evidence relevant to the assessment of social mobility , in particular, intergenerational class mobility , in contemporary Britain through cross-cohort analyses based on the NCDS and BCS datasets which we can relate to earlier cross-sectional analyses based on the GHS. We find that, contrary to what seems now widely supposed, there is no evidence that absolute mobility rates are falling; but, for men, the balance of upward and downward movement is becoming less favourable. This is overwhelmingly the result of class structural change. Relative mobility rates, for both men and women, remain essentially constant, although there are possible indications of a declining propensity for long-range mobility. We conclude that under present day structural conditions there can be no return to the generally rising rates of upward mobility that characterized the middle decades of the twentieth century , unless this is achieved through changing relative rates in the direction of greater equality or, that is, of greater fluidity. But this would then produce rising rates of downward mobility to exactly the same extent , an outcome apparently unappreciated by, and unlikely to be congenial to, politicians preoccupied with winning the electoral ,middle ground'. [source] UNCONVENTIONAL MONETARY POLICIES: AN APPRAISALTHE MANCHESTER SCHOOL, Issue 2010CLAUDIO BORIO This paper sets out a framework for classifying and thinking about unconventional monetary policies, highlighting how they can be viewed within the overall context of monetary policy implementation. The framework clarifies the differences among the various forms of unconventional monetary policy, provides a systematic characterization of the wide range of central bank responses to the recent crisis, helps to underscore the channels of transmission and identifies some of the main policy challenges. In the process, the paper also addresses a number of contentious analytical issues, notably the role of bank reserves and their inflationary consequences. [source] | |||||||||||||
